Character

Mytyl Kamizono

神園ミチル

Mytyl is Copen’s twin (younger) sister, who like her twin brother, does not possess any septimal powers. Due to her weak constitution, she spends her days living in a long-term medical care facility. She has been extremely frail since birth, and due to a surgery she had at a very young age, she lost her voice and now communicates with people via a tablet. Likely due to her frail constitution and being long-term medical care, she is quite small in stature, which gives many people the impression that she and Copen were born many years apart, but they are in fact the same age. Copen does not speak to her at all about his battles.
